I just updated Firefox and I can't change my Theme back to what I had it on.... It's says 'disabled' and when I try to enable it, nothing happens at all... How can I fix this??

doesnt work anymore

This was a great extension before Firefox updated to the Quantum version. Most of the functionality is now gone and the extension is basically worthless.

It's currently useless. All the great features it used to provide in past versions are gone due to the release of Firefox Quantum. I hope the author finds a way to bring them back in the future.

No longer working for the new version of Firefox.
I will review my rating once fixed, as of now, dont bother.

Keine Schriftgößenveränderung ab firefox 57 in Menüleiste

Wow, way to ruin a perfectly fine extension. I know it wasn't your idea to kill perfectly functioning browser, but hell, you could have just told the users NOT to use it anymore, like so many extensions do, with the new firefox.

The date bomb for this add-on is now in effect, and the add-on will no longer function in Firefox, unless you either roll back your system date, or, the instructions here may help you: http://tl.gd/n_1sqcu4r

Again, to the developer: There are XUL variants of Mozilla that people are now using, such as Waterfox and Basilisk. Please make a separate XUL based version of your legacy plugin for those users, and separate out this crippled version for Web Extension only versions of Mozilla (i.e., Firefox 57+). And please remove the date bombs, there are not the slightest bit necessary or user friendly for that matter.

Using Firefox 57, the extension options says "Because of the new extension system on Firefox, most of the functionality of the Theme Font & Size Changer is not available any more"...
...so why is it even available for Firefox 57 if it's not doing anything at all (definitely no changes of fonts & sizes)??

It doesn't work anymore. You can't change the font size. You can't even change the color.

Semmire sem használható!

My previous review was deleted by somebody. I am posting it again. Version 62 does not work, you have to revert to Version 56 and stop the damn thing from updating by going to addon, and "more" and select auto update to "OFF". This is a very useful addon which I am sure helps a lot of people. Doing an update to version 62 which does not work is a useless thing to do. Deleting comments is basically dishonest.

Garbage! Absolutely GARBAGE!

Forcing an update to a no functioning extension.

Guess what, FF isn't supporting extensions anymore, so here's an update that breaks my extension on purpose. Oh and take this survey where you have to leave your email address so I can spam you.

v62 is no good , back in v56 and work fine

DOWNLOADED AND INSTALLED. CLICKED THE ICON AND READ THIS:
"Because of the new extension system on Firefox, most of the functionality of the Theme Font & Size Changer is not available any more"
WHY IS THIS AVAILABLE AS A DOWNLOAD IF IT'S NOT AVAILABLE ANY MORE? I'M USING THE LATEST FIREFOX.

This was the only way I was able to use Firefox comfortably. Firefox 57 ended all that. The reason I used FF was because it's customization. I understand what FF is trying to do, but it has turned it into Chrome or Edge...UGH! So I reverted to version 56. I thought TF&SC would then, but no luck. Is there a way to make it work for older versions of FF?

Loved this until 57 was released.

But here's a question.

If you look at the page for T&FSC, it says it was updated on November 16.

Yet it still doesn't work with 57 which was released 2 days BEFORE.

What gives?

Please make available for Firefox 57. I know it's not your fault that this extension doesn't work anymore and that Mozilla's latest Firefox makes it incompatible. I've been using this Add on for many years and, like a lot of other folks with aging eyesights badly need it. Shame on Mozilla for not only making you incompatible but for also giving the middle finger to us older users by making their menu items unreadably small.

Can not change the font size.

It was hard to find the button under FF57, and then when I found it I discovered that this addon no longer does what it used to do, which is make Firefox usable for me. Very disappionted. Not your fault, I know. The only workaround I found was given here: https://support.mozilla.org/en-US/questions/1184537, and involves changing about:config values.

I can't tell you how much I hate you for changing my Firefox v51 back to tiny font just because you are having trouble with v57. What made you do such a shitty thing?
